TPS61031PWPR TI DC-DC Converter | 16-HTSSOP | 3.3V Output, 1.8A Switch

Product Overview

The TPS61031PWPR from Texas Instruments is a high-frequency, synchronous boost converter with a 1.8A integrated switch. It provides a regulated output voltage of 3.3V from a single-cell Li-Ion battery or two-cell alkaline/NiMH batteries. The device operates at a fixed 1.2MHz switching frequency, allowing the use of small external components. The TPS61031PWPR is available in a 16-pin HTSSOP package with PowerPAD for enhanced thermal performance.
